@pipeworx/wikidata-sparql

Wikidata Query Service MCP — full SPARQL access to the entire Wikidata knowledge graph (~100M items, 1.5B statements). Complements the existing wikidata pack (which covers entity search + retrieval).

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Tools

• query(sparql, format?) — run a SPARQL query

• instances_of(entity_id, limit?) — convenience: all instances of a class (e.g. Q5 = humans)

• subclasses_of(entity_id, limit?) — convenience: subclass tree

• properties_of(entity_id, limit?) — convenience: statements about an entity

• entities_at(latitude, longitude, radius_km?, instance_of?, limit?) — geo-spatial query: items near a point

No auth

The public WDQS at https://query.wikidata.org/sparql is keyless. Fair-use: ≤30 queries / min, ≤60 sec timeout per query. The pack sets a meaningful User-Agent (required by WMF policy).

Tips

Wikidata is enormous — narrow your queries! Use LIMIT, instance of filters, and language tags. Bring schema knowledge from https://www.wikidata.org/wiki/Wikidata:List_of_properties.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "wikidata-sparql": {
      "url": "https://gateway.pipeworx.io/wikidata-sparql/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Wikidata Sparql data" })

The gateway picks the right tool and fills the arguments automatically.
